STMP1 / STMP157-OLinuXino-LIME2 hangs ...

Last post by lucw650 - September 15, 2025, 07:51:14 PM

When I power up my (new) STM32MP1 board it hangs in u-boot.

Init AXP209 PMIC
VDD Core set to: 1350 mv

There are some threads on this forum, but no solution.

When I use the image in the folder TEMP/LIME2-NO-AXP209 it boots normal, however I do not have HDMI output after installing xfce.

Thanks

I can't say about the pull ups and pull downs.

Yes, you need to free the from other software functions before declaring for the function you need.

You can get A20-OLinuXino-MICRO, it doesn't have a JTAG connector but you can use standard jumper wires to establish hardware connection:

My advice is to find experience with any board using OLIMEX ARM-USB-OCD-H. I know there are RPi guides and other board guides.

It is very difficult to program Linux via JTAG, JTAG is usually used for general-purpose code, not OS. JTAG programming of Linux boards is most commonly used either in production environment to save time on programming, or only as last resort trying to recover something. It requires a lot of knowledge. Imagine programming your personal computer via a tool, imagine tracking registers and addresses and programming binary code.

Thanks for your answer. The thread you linked is about the memory issue, which I luckily was already able to solve. I am really looking for the reason why the core itself won't start.

My advice is to search and then post in the NXP forums. I see similar error massages in this thread here:

NXP / Programming M core on iMX8MP

Last post by jospuntnl - September 12, 2025, 02:44:13 PM

Hi,

I've been trying to program the M-core of the IMX8MP for a while now, and after messing around with memory adresses, I've finally got a firmware file that does not immediately get rejected. Sadly I've ran into another issue:

Code Select Expand

[  412.455146] remoteproc remoteproc0: powering up imx-dsp-rproc
[  412.462385] remoteproc remoteproc0: Booting fw image hello_world.elf, size 185848
[  412.585249] remoteproc remoteproc0: can't start rproc imx-dsp-rproc: -110
[  412.585353] remoteproc remoteproc0: Boot failed: -110

Can anyone tell me what's wrong? I'm running the official minimal Debian OS, on the official evaluation board.

All,

I just want to get a board that can boot Ubuntu 22.04, 24.04. Fedora .. . with a JTAG connector on it.  I already have an ARM Olimex USB-OCD-USB-H board and I want to use it with this board.

Any recommendation?
I just want to learn OpenOCD. 

Thank you!

As you noticed by default SAM9-L9260 comes prepared with Linux. This Linux image and sources can be found in this this ISO - mount it and explore the contents inside:

https://ftp.olimex.com/Obsolete_images/SAM9-L9260/SAM9-L9260_Rev.D.iso

Notice that SAM9-L9260 is not a personal computer, it will not boot Ubuntu 22.04 from a flash drive.

Yeah you can also use jumper wires at the UEXT to save from soldering. Just change the definitions, look at the schematic for the GPIOs of the ESP32 at the UEXT.

This is where I saw about 1106, one of the pictures on the product page:

New Product Ideas / SAM9-L9260 board / Boot to an ...

Last post by TomH - September 08, 2025, 08:37:16 PM

Hello,
I recenty got an Olimex SAM9_L9260 board.  After connecting to a 5V/3A power supply, connecting to a null modem, Hyperterminal, I got the board to boot and was able to login.

Now my questions are:
1. The box the board came in is empty.  No quick starting quide.  How do I format / boot to an OS on my SD card?  I tried to format a 128 MB SD card using Rufus and put Ubuntu 22.04 on it.  No go.

2.  Is / Are there any jumper(s) I can set so it will boot to SD/MMC card.  I see this in the SAM9_L9260 file:
Is the SD/MMC card supported?
A: The SD/MMC card is fully supported, including detection of card insertion/removal and
write lock

3. I also saw this in the PDF file.  Where is the NANDF_E and DF_E jumpers are located?
A: Make sure that NANDF_E jumper is not connected and DF_E jumer is connected. If the
dataflash has been correctly programmed, the board should start up

4.  I got this from https://www.olimex.com/wiki/SAM9-L9260

git clone -b olimex https://github.com/OLIMEX/at91bootstrap.git

and when I tried to build it using:
 make sam9_l9260_uboot_defconfig

this does not work.

What's the latest instruction?
